FIG. 2 is a flowchart illustrating a method of acquiring additionalinformation according to various embodiments of the present disclosure.

Referring to FIG. 2, in operation 201, the controller may control thedisplay unit to display a preview image. Here, the preview image meansan image displayed on the display unit through driving of the camera.The controller may collect situation information at a time of thedisplay of the preview image in operation 203. The collected situationinformation may include information about a subject included in thepreview image and/or surrounding situation information about theelectronic device, for example, weather information about acorresponding location acquired by receiving location informationthrough the GPS receiver, beat and/or noise information about a soundreceived through the audio processor, and brightness informationdetected by a luminance sensor. Particularly, the subject may be aperson or may not be a person according to an embodiment of the presentdisclosure.

When the subject is a person, the information about the subject mayinclude facial expression information about the person, shared sensorinformation (for example, pulse sensor information) of anotherelectronic device, e.g., a wearable device, connected with an electronicdevice used by the person, and information received through an SNS ofthe person.

When the subject is not a person, for example, an object, theinformation about the subject may include information about the subject,for example, a vehicle, the sea, and a mountain.

Operation 203 illustrated in FIG. 2 will be described in detail withreference to FIG. 3. FIG. 3 is a flowchart illustrating a configurationof collecting situation information according to various embodiments ofthe present disclosure.

Referring to FIG. 3, the controller may receive information about asubject in operation 301. The controller may acquire locationinformation from the GPS receiver and confirm weather information aboutthe location in operation. The controller may receive SNS informationabout the subject in operation 305. Particularly, when the subject is aperson, the controller 180 may receive SNS information connected to theperson (for example, emotion information registered in the SNS). Thecontroller may also receive sound information through the audioprocessor in operation 307. For example, the sound information mayinclude beat and/or noise information of a sound. Next, the controllermay detect a brightness degree through the luminance sensor in operation309.

In the embodiment of the present disclosure, the controller may receivethe one or more pieces of information through operations 301 to 309, andperform an operation of analyzing weighted values assigned to thereceived situation information in operation 311. Different weightedvalues may be assigned to the respective situation information, or theweighted value may be graded and assigned based on situation informationwhich a user considers important. For example, a weighted value assignedto a subject is 0.4, a weighted value assigned to weather information is0.2, a weighted value assigned to brightness information is 0.1, aweighted value assigned to sound information is 0.1, and a weightedvalue assigned to SNS information is 0.2, and a large weighted value maybe assigned to situation information to be considered important in orderto determine shutter attribute information.

Referring back to FIG. 2, the controller may combine the analyzedinformation about the subject and the weighted value of the situationinformation, and extract shutter attribute information in operation 205.The shutter attribute information may be determined according to thesubject. When the subject is a person, the shutter attribute informationmay be emotion information, for example, happy, said, and excited. Whenthe subject is not a person, that is, the subject is an object, theshutter attribute information may be object information, for example, avehicle, the sea, a mountain, trip, and a dog). But the shutterattribute information, though, is not limited to those listed above.

The extracted shutter attribute information may then be corrected basedon accumulated shutter attribute information. Particularly, the shutterattribute information, for example, the shutter attribute informationdetermined by the controller and/or the shutter attribute informationdetermined by an adjustment of a user, determined according to thesituation information may be accumulated and stored. When situationinformation, which is the same as, or similar to, the previous situationinformation, is generated later, the controller may analyze a storedhistory and extract shutter attribute information according to theanalyzed history.

The controller may determine and display a shutter button, to which aparameter corresponding to the extracted shutter attribute informationis applied, in operation 207. The parameter, which is a mediumcorresponding to the shutter attribute information, may be displayedwhile being reflected to the shutter button, and a user may visuallyconfirm extracted emotion information through the shutter button towhich the parameter is reflected. The controller may determine whetherthe shutter button is adjusted in operation 209. For example, anoperation of adjusting the shutter button may be adjusting the shutterbutton to a shutter button desired by the user when the shutter buttonof the parameter determined according to the situation information isnot emotion information desired by the user.

When the shutter button is adjusted, the controller may adjust theshutter button in operation 211. After the operation of adjusting theshutter button is performed, or when the operation of adjusting theshutter button is not generated in operation 209, the controller maydetermine whether to photograph the preview image with the determinedshutter button in operation 213. When a photographing demand isgenerated, for example, a user's selection for the shutter button isinput, the controller may photograph the preview image andsimultaneously store the photographed image, and situation informationand shutter attribute information about the image together in operation215.

Situation information and shutter attribute information fields may begenerated in additional information Exif within the image and thesituation information and the shutter attribute information may berecorded and stored. The present disclosure is not limited thereto, andthe situation information and the shutter attribute information may alsobe stored in a format, in addition to the additional information Exif.The controller may determine whether to terminate the operation inoperation 217. When a termination command is generated, the controllermay terminate the driving of the camera. However, when the terminationcommand is not generated, the controller may return to operation 201,and control the display unit to display a preview image.

FIG. 4 is a diagram illustrating a configuration of processing an imageaccording to various embodiments of the present disclosure.

Referring to FIG. 4, an image processor 410 processes an image signaloutput from the camera into a digital image, and pre-processes andpost-processes image data. The image processor 410 may include an imagepre-processing/post-processing unit, a scaler for generating an image(hereinafter, a display image) obtained by scaling an image with a setdisplay size of the display unit, and/or a codec for compressing andencoding image data. Next, a face recognizing operation is performedbased on the image processed by the image processor 410 in operation420, and position information and size information about the eyes and/orthe mouth in the face may be obtained by the face recognizing operation.

The controller may extract emotion information by analyzing the obtainedposition information and size information about the eyes and/or themouth in the face in operation 430. For example, when the facialexpression is determined as a smiling expression through the analysis ofthe obtained position information and size information about the eyesand/or the mouth in the face, the controller may extract the emotioninformation of “happy”.

Otherwise, the controller may extract emotion information according toshared sensor information. For example, a pulse rate detected by a pulsesensor, or another electronic device (for example, a wearable device)connected with the electronic device. The controller may also analyzesurrounding situation information about the electronic device receivedthrough the sensor unit, the GPS receiver, and the audio processor andextract emotion information. The controller may analyze the emotioninformation extracted through the facial expression and the emotioninformation extracted through the situation information, and determinefinal emotion information in operation 440. The controller 180 thendetermines and displays a shutter button corresponding to the extractedemotion information in operation 450. In the embodiment of the presentdisclosure, when a touch event is generated in the shutter button, thecontroller may photograph the image, and simultaneously store thephotographed image and the emotion information about the image.

FIG. 5 is a flowchart illustrating a method of acquiring additionalinformation according to various embodiments of the present disclosure.In the disclosed example, the shutter attribute information is emotioninformation

Referring to FIG. 5, the controller may collect information about asubject (i.e., a person) included in a preview image displayed on thedisplay unit through driving of the camera and/or situation informationat a display time of the preview image and extract emotion information.Further, the controller 180 may determine and display a shutter buttonto which an emotional parameter corresponding to the extracted emotioninformation is applied.

In operation 501, the controller may control the display unit to displaya preview image. Here, the preview image means an image displayed on thedisplay unit when the camera is driven. Next, the controller may collectsituation information at a display time of the preview image inoperation 503. The collected situation information may includeinformation, e.g., expression information about a person and informationreceived from an SNS of a person about a person included in the previewimage, and/or surrounding situation information, e.g., weatherinformation about a corresponding location acquired by receivinglocation information through the GPS receiver, beat and/or noiseinformation about a sound received through the audio processor, andbrightness information detected by the luminance sensor about theelectronic device.

Operation 503 illustrated in FIG. 5 will be described in detail withreference to FIG. 6. FIG. 6 is a flowchart illustrating a configurationof collecting situation information in order to determine shutterattribute information according to various embodiments of the presentdisclosure.

Referring to FIG. 6, the controller may receive information about asubject in operation 601. Particularly, the controller may recognize aface of a person in the preview image acquired through the camera, andacquires position information and size information about eyes and/or amouth on the face. The controller may then extract emotion informationabout the person by analyzing a facial expression through the acquiredinformation.

Further, the controller may acquire location information through the GPSreceiver and confirm weather information about the location in operation603. The weather information may include sunny, cloudy, rain, snow, andthe like. The emotion information, e.g., happy and sad, may be extractedaccording to the weather information.

SNS information about the person is received by the controller inoperation 605. The controller receives SNS information when an SNS ofthe person displayed on the preview image is connected. For example, theSNS information may include emotion information registered in the SNS,and when a plurality of pieces of emotion information is registered, thecontroller may receive recently registered emotion information. Thecontroller may receive shared sensor information, for example, a pulsesensor information, of another electronic device, a wearable device,connected with an electronic device used by the person in operation 606.When a pulse rate is fast based on the shared pulse sensor information,the controller may extract emotion information, for example, “excited”or “satisfied”, according to the pulse rate. When a pulse rate is slowbased on the shared pulse sensor information, the controller may extractemotion information, for example, “calm” or “tired”, according to thepulse rate.

The controller may receive sound information through the audio processorin operation 607. The sound information may include a noise degree andnoise beat information about a photographed place. For example, when itis determined that a noise degree is large and/or a noise beat period isshort through the sound information, the controller may extract emotioninformation, for example, “excited” or “satisfied”, according to thedetermination. When it is determined that a noise degree is small and/ora noise beat period is long through the sound information, thecontroller may extract emotion information, for example, “calm” or“tired”, according to the determination.

The controller may also detect a brightness degree through the luminancesensor in operation 609. The controller may extract emotion information,for example, “happy”, “sad”, or “gloomy”, according to a brightness ordark degree detected through the luminance sensor.

In the embodiment of the present disclosure, the controller may receiveone or more pieces of information through operations 601 to 609, andanalyze a weighted value for the one or more pieces of receivedinformation in operation 611. Different weighted values may be assignedto the respective situation information, or the weighted value may begraded and assigned based on situation information which a userconsiders important.

Referring back to FIG. 5, the controller may combine weighted values ofthe analyzed situation information and extract emotion information inoperation 505. In the embodiment of the present disclosure, exampleemotion information may include emotions listed in Table 1.

TABLE 1 Category Term Pleasure Pleased, happy, glad, delightedExcitement Excited, astonished, delighted, aroused Arousal Aroused,angry, alarmed, tense, astonished Distress Distressed, afraid,frustrated, annoyed Misery Miserable, gloomy Depression Depressed,gloomy, sad, bored Sleepiness Tired, sleepy, droopy, bored ContentmentSatisfied, content, calm, relaxed, at ease, serene

For example, when a weighted value for a subject is 0.4 and emotioninformation is happy, a weighted value for weather information is 0.2and emotion information is sad, a weighted value for brightnessinformation is 0.1 and emotion information is sad, a weighted value forsound information is 0.1 and emotion information is happy, and aweighted value for SNS information is 0.2 and emotion information ishappy, the controller may analyze the emotion information according tothe assigned weighted values and extract the emotion information of“happy”. The numerical value of the weighted value is one example, andthe weighted value is not limited thereto.

The controller may determine and display a shutter button, to which anemotional parameter corresponding to the emotion information extractedin operation 505 is applied, in operation 507. Here, the shutter button,to which the emotional parameter is applied, may be a button to which anicon and an emoticon corresponding to the emotion information areapplied.

The controller may then determine whether the shutter button is adjustedin operation 509. For example, an operation of adjusting the shutterbutton may be adjusting the shutter button to a shutter button of theemotional parameter desired by the user when the emotion informationdetermined according to the situation information is not emotioninformation desired by the user.

When the shutter button is adjusted, the controller may detect theadjustment of the shutter button in operation 509 and adjust the shutterbutton in operation 511. Next, after the operation of adjusting theshutter button is performed, or when the operation of adjusting theshutter button is not generated in operation 509, the controller maydetermine whether to photograph an image in operation 513. When aphotographing demand is generated, the controller may store thephotographed image and the situation information and the emotioninformation about the photographed image together in operation 515.Situation information and shutter attribute information fields may begenerated in additional information Exif within the image and thesituation information and the shutter attribute information may berecorded and stored.

It should be noted that the situation information and the shutterattribute information may also be stored in a format in addition to theadditional information Exif. Then, the controller may determine whetherto terminate the operation in operation 517. When a termination commandis generated, the controller may terminate the driving of the camera.However, when the termination command is not generated, the controllermay return to operation 501, and control the display unit to display apreview image.

FIGS. 7A and 7B are exemplary diagrams for describing a method ofacquiring additional information according to various embodiments of thepresent disclosure.

Referring to FIGS. 7A and 7B, reference numeral 701 of FIG. 7A denotesshutter buttons to which emotional parameters corresponding to extractedemotion information are applied. When an event is generated in theshutter button, emotion information corresponding to an emotionalparameter may be stored together with an image. Further, one or moreshutter buttons 701 may be vertically adjusted as denoted by referencenumeral 703.

When a preview image including a person is displayed on the touch screenthrough driving of the camera as illustrated in FIG. 7A, the controllermay acquire position information and size information about eyes and/ora mouth of a person in the preview image and analyze a facialexpression. The controller may extract emotion information through theanalyzed facial expression. For example, the controller may determinethe facial expression as a smiling expression through the analysis ofthe facial expression of the person included in the preview image asillustrated in FIG. 7A, and thus extract emotion information of “happy”.

The controller may extract weather information about a correspondingregion at a display time of the preview image, surrounding brightnessinformation, surrounding sound information, and emotion informationabout a person, and/or shared sensor information, e.g., pulse sensorinformation of another electronic device, e.g., a wearable device,connected with the electronic device. The controller 180 extracts finalemotion information based on the extracted information and may displaythe shutter button, to which the emotional parameter corresponding tothe extracted emotion information is applied, in a center region asdenoted by reference numeral 705.

As described above, when the emotion information of “happy” isextracted, the controller may display a “happy” shutter buttoncorresponding to the emotion information of “happy” in the centerregion. When a photographing event is generated in the displayed “happy”shutter button, the controller may store the emotion information of“happy” and the situation information together with the photographedimage. In the embodiment of the present disclosure, the emotioninformation of “happy” and the situation information may be recorded inadditional information Exif within the image.

Otherwise, the emotional parameter for the emotion information of“happy” may be displayed with various kinds of emotional emoticons asdenoted by reference numeral 707, illustrated in FIG. 7B, and thus, auser may widely apply emotion information for the image by utilizing thevarious emoticons.

FIG. 8 is a diagram of an example case where a stored image is displayedaccording to shutter attribute information in accordance with variousembodiments of the present disclosure.

Referring to FIG. 8, the photographed image obtained by photographingthe image may be classified based on emotion information and stored in agallery. Particularly, the controller may generate a folder according tothe emotion information about the photographed image in the gallery, andstore the photographed image in the generated folder. In the embodimentof the present disclosure, when a folder according to emotioninformation is previously generated, the controller may store thephotographed image in a folder mapped to emotion information about thephotographed image. For example, when a “happy” folder is generated, theimage, from which the emotion information of “happy” is extracted, maybe classified into and stored in the happy folder. Then, a user may viewthe images, to which the emotion information of “happy” is reflected,through the happy folder stored in the gallery.
